Additional Notes

  • The Hyundai Sonata YF (USA) cooling system capacity is 6.6 liters across the 2.0T GDI and 2.4 GDI engine variants for 2011-2014, a figure consistent with a full service fill of the entire cooling circuit rather than a partial top-up volume.
  • On the 2.0T GDI and 2.4 GDI configurations, the normal-use coolant change interval is 30,000 miles or 24 months, whichever comes first.
  • The first-change-only interval for the 2.0T GDI and 2.4 GDI extends to 60,000 miles or 60 months, reflecting the longer service life of the factory-fill coolant before the standard recurring schedule takes effect.
  • The 2.4 Hybrid HEV combustion engine cooling system carries a capacity range of 6.6 to 6.9 liters for 2011-2014, a slight spread above the fixed 6.6-liter figure seen in the non-hybrid variants.
  • On the 2.4 Hybrid HEV, the first-change-only interval for the combustion engine cooling system is 120,000 miles or 120 months, which is double the 60,000-mile or 60-month first-change interval specified for the non-hybrid 2.0T GDI and 2.4 GDI engines.
  • The 2.4 Hybrid HEV carries a separate inverter cooling circuit with a capacity of 2.26 liters, a substantially smaller volume than the combustion engine circuit, corresponding to the more compact thermal management loop serving the power electronics.
  • The inverter cooling system on the 2.4 Hybrid HEV shares the same normal-use interval of 30,000 miles or 24 months as the combustion engine circuit, and also shares the same first-change-only interval of 120,000 miles or 120 months.
